PROCESS FOR PREPARATION OF HEXAFLUOROACETONE MONOHYDRATE

摘要

Disclosed is a method for producing hexafluoroacetone monohydrate by (1) allowing, in an organic solvent, hexafluoroacetone to be absorbed into water or a hexafluoroacetone hydrate (water addition method) or by (2) an easy method in which a hexafluoroacetone hydrate is mixed with an organic solvent and then distillation is conducted, thereby removing a mixture of water and the organic nnnt as a low-boiling-point composition and obtaining a mixture of hexafluoroacetone monohydrate and the organic solvent as a high-boiling-point composition (dehydration method).
